Raman studies of the bending and librational bands from water and ice VI to ∼12 kbar at 32°C

Raman data have been obtained from water and ice VI in the region from about 300–4000 cm−1 to pressures near 12 kbar at 32°C. Little, if any, hydrogen-bond breakage is indicated, in agreement with thermodynamic results. Some implications of Fermi resonance are discussed.
